The secondary turboculvert electric drive engine comprises an engine shell cover, a vortex pressure air channel and a tail jet pressure air channel which are sequentially arranged in the air flow direction are formed in the engine shell cover, and an air jet opening is formed in the tail end of the tail jet pressure air channel; a motor and a core shaft which are in linkage are arranged in the engine shell cover, rotating fan blades and a secondary turbine used for rectifying and recycling vortex energy are sequentially arranged on the core shaft in the airflow direction, and the secondary turbine is located at the tail end of the vortex pressure air channel. According to the secondary vortex culvert electric drive engine, efficient recycling of vortex energy is achieved, meanwhile, impact of vortex force on the air deflector support is greatly reduced, and the secondary vortex culvert electric drive engine is more energy-saving, lower in noise, better in stability and longer in service life.
本发明公开了一种次级涡涵电驱发动机,包括发动机壳罩,发动机壳罩内设有沿气流方向依次布置的涡流压气道和尾喷压气道,尾喷压气道末端设有喷气口;发动机壳罩内设有相联动的电机和核心轴,核心轴上沿气流方向依次设有转动扇叶和用于整流和回收涡旋能量的次级涡轮,次级涡轮位于涡流压气道的末端。本发明提供的次级涡涵电驱发动机,实现了对涡旋能量的高效回收利用,同时大幅降低涡旋力对导风板支架的冲击,而且更节能,噪音更低、稳定性更好,使用寿命更长。
